This work contains the contribution of 18 tutorials of the 11th Workshop on Advances in Analog Circuit Design, providing information and overviews of analogue circuit design, CAD, and RF systems. These books can be seen as a reference to those people involved in analogue and mixed signal design. The idea is to discuses in each book three specific to-date topics on new and valuable design ideas in the area of analog circuit design. Each topic is discussed by six experts in that field and state of the art information is shared and overviewed. In this 11th edition the topics are: structured-mixed-mode design, multi-bit sigma-delta converters and short range RF circuits.
